HORSESHOE-MAKING MACHNE.

Application filed November 23, 11822. Serial No. 602,769.

To @ZZ Iwhom t may concer/IL:

Be it known that I, MARGL Bauens, citizen of the Republic of France, residing at Santiago de Chile, have invented new and useful improvements in Horseshoe-Making Machines, of which the following is a specilic-ation.

This invention relates -to an improved nia-- chine for bending metal bars, the object of the invention being to pro-vide a machineof this character by means of which metal blanks that have been previously rolled and cut to the required dimensions may be uniformly bent into the desired shape without the production of the completed article is accomplished expeditiously and economically, the machine being particularly well adapted for the formation of horseshoes and similar articles.

With the foregoing and other objects in view, which will appear as the description proceeds, the invent'on consists in the novel features of construction and combination of parts which will be more fully described hereinafter and particularly pointed out in the claims.

In the drawings accompanying and formino: part of this specification:

' Fig. 1 is a plan view of a machine embodying the features of the present invention;

Fig. 2 is a vertical sectional view taken on the line A-B of Fig. 1; and

Fig. 3 is a vertical sectional on the line C-D of Fig. 1.

The same characters of reference designate the same parts in the different figures of the drawings.

Referring to the drawings, 23 designates a standard or pedestal, preferably of hollow formation, as indicated at 23, said sta ndaid merging at its lower end in a flanged base 23 adapted to be secured by means of bolts 25 to a suitable foundation (not shown). At its upper end the pedestal merges into an enlarged head or platform 24., the upper surface of which is cut away at one portion thereof to receive a work table of approximately semicircular form, which is secured to the head 211 by means of bolt-s 26, the top surface of the table 13 being in the same horizontal plane with the top surface of the extended table portion of the head, The pedestal is pl'QViCll with view taken kthus constituting webs 28 and 30 for giving addition al support to the table portions 13 and 15.

The table 13 is provided with a guide slot lll of approximately horseshoe shape, within which operates a roller 2 pivoted on a stud 3 secured in a pair of bifurcated members 1 which are fastened by bolts and nuts et to an operating handle 5, the members 1 and 5 a hand lever adapted to fulcrum on the walls of the slots 141 in the table. As clearly shown in Fig. 2, the members 1 are spaced sufficiently far apart to straddle the table 13. overlies the table 13 is of enlarged formation, forming a cam-like nose at its inner ends, as shown in Fig. 1.

Secured in the table 13 and extending up`- wardly therefrom are a pair of studs 12 located in the space encompassed by the slot 111, said studs being threaded at their upper ends lto receive nuts 12. The studs 12 carry a vertically movable presser head 8 and a pressure receiving member 8. Through the head 3 is `threaded a pressure screw 11, the lower end of which rests on the pressure receiving member 8, said screw being provided at its upper end with a cross lever 9 carrying a pair of operating handles 10 by means of which the screw 11 may be rotated to exert pressure on the member 8. The studs 12 are of such length as to provide space between Pthe underside of the member 8 and the table 13 for the reception of a pattern or model 6 and an overlying member or cover 7 of greater width than said pattern whereby the member 7 overhangs the pattern around its edge so as to form a marginal space between the table 13 and the member 7 around the edge of the pattern 6. The said pattern is provided with a heel or stop portion 27 for engaging the end of the metal bar to be bent, as deie'nafter de scribed.

For securing the metal to be operated upon in the machine, a curved detent mein ber or dog 17 is pivoted at 1S on the table 13 in such position that its free end is adapted to be swung under the member T and into engagement with the pattern at a point contiguous to the stop portion 27, and for exerting pressure on said detent member a screw 19 is mounted in brackets 20 and 21 secured to the table 13, said screw being thread connected with bracket and proV The member 1 that l (ll) vided at its outer end with a hand lever 22 for rotating the screw. p

Ther operation of theA machine is as follows: The nuts l2', together with the' members 8, 8 and 7 are removed from the studs 12. A plate or pattern 6, the contour of which corresponds to the shape to which it is desired to bend the metal bar, is then placed in position on the table, the pattern being` provided With a pair of perfo-rations for the passage ot the studs l2. The meinbers 7, 8 and 8, as Well as the nuts l2 are then replaced and the screw 1l. rotated by means of thehandles l0 sof as to exert pressure on the pressure receiving` member tl and thereby'securely clamp the pattern in place. A blank 1.6, which has been previously rolled to thejproper tl'iickness and cut to the exact length required, is inserted 'with one. of its eXtreme ends between the 'free en'd el the detent 17 and the edge of the pattern, said blank being pushed in until its inner end abuts against the stop or abut-- ment 27,. Where-upon the screw 19 is rotated by mea-ns of its lever 22- thereby to exert pressure Von the detent 17 and cause it to se- Y curely clamp the end vot the blank 1G against the edige of the pattern 6l and beneath the overhainging edgel of the member 7. The operator thenta'lres hold ot the lever 5, and by asuccessien of short reciprocatingI strokes during. which the roller 2 fulcruins against the Vside Walls of the slot 14 inl the table 13 the earn-like nose' lof the lever engages the blank 16' at successive points and forces it into intimate Contact with the pattern, inl a manner which Will 'be readily understood. After thev arti-cle has been completely formed, the members S, S and T are released from the studs so as to permit the pattern to be lifted and the formed article removed from the machine.

It will be understood, of ceurse, that patterns of various sizes and shapes may be used, and although for purposes of illustration the machine has been described in connection with the formation of a horseshoe, it is by no means limited thereto.

Having thus described my what I claim is: Y

l. A machine for bending metal blanks, comprising, table, meansior securing a pattern onrsaid table, means for securin .g` yone end of a blank against the pattern, andy a lever adapted to engage said blank at successive points and force the saine into contact with the pattern, said lever and table having one a slet and the other a roller adapted to engage the Walls et the slot thereby to guide said lever and form `a fulcrurn therefor.

2. A machine for bending` metal bars, comprising, in combination, a supporting table, means for securingv a pattern en said table, means for securing one end ot a blank against the pattern, anda lever adapted to engage said blank at successive peints and force the same into contact with the pattern, said table having,T a slot encompassing said pattern and saidl'everhav'ing' a reller projecting into said slot and adapted toengage the Wallsthcre'of thereby' toy guide the lever andy forni a ul'cruml therefor.

invention,

ln testimony whereof I have signed.
